            Certain aspects of GL behavior,
            when there is room for interpretation,
            can be controlled with hints.
            A hint is specified with two arguments.
            <em class="parameter"><code>target</code></em> is a symbolic
            constant indicating the behavior to be controlled,
            and <em class="parameter"><code>mode</code></em> is another symbolic constant indicating the desired
            behavior. The initial value for each <em class="parameter"><code>target</code></em> is <code class="constant">GL_DONT_CARE</code>.
            <em class="parameter"><code>mode</code></em> can be one of the following:
        </p><div class="variablelist"><dl class="variablelist"><dt><span class="term"><code class="constant">GL_FASTEST</code></span></dt><dd><p>
                        The most efficient option should be chosen.
                    </p></dd><dt><span class="term"><code class="constant">GL_NICEST</code></span></dt><dd><p>
                        The most correct,
                        or highest quality,
                        option should be chosen.
                    </p></dd><dt><span class="term"><code class="constant">GL_DONT_CARE</code></span></dt><dd><p>
                        No preference.
                    </p></dd></dl></div><p>
            Though the implementation aspects that can be hinted are well defined,
            the interpretation of the hints depends on the implementation.
            The hint aspects that can be specified with <em class="parameter"><code>target</code></em>,
            along with suggested semantics,
            are as follows:
        </p><div class="variablelist"><dl class="variablelist"><dt><span class="term"><code class="constant">GL_GENERATE_MIPMAP_HINT</code></span></dt><dd><p>
                        Indicates the quality of filtering when generating mipmap images with

            The interpretation of hints depends on the implementation.
            Some implementations ignore <code class="function">glHint</code> settings.
        </p></div><div class="refsect1"><a id="errors"></a><h2>Errors</h2><p>
            <code class="constant">GL_INVALID_ENUM</code> is generated if either <em class="parameter"><code>target</code></em> or <em class="parameter"><code>mode</code></em> is not
            an accepted value.
